How Does An Ac Parts Compressor Work?

The function of an air conditioner in a HVAC is to provide cool air to the rooms. It does this through a process of heat transfer. At the centre of the air conditioner cooling prices is a refrigerant compound. The air conditioner converts the refrigerant compound from gas into liquid and back a gain to continuous cycle which generates cooling. The four major parts of an air conditioner are a compressor, condenser, expansion valve, and evaporator. Here we will take a look at how the compressor of an A/c works?

The compressor can be compared to a human heart. Its basic job is to pump the refrigerant through relevant tubes in an A/c after compressing it. This is very similar to the human heart that pumps blood to various parts of the human body. The cycle of an A/c begins when cool refrigerant gas reaches the compressor from the evaporator. The compressor compresses the gas and raises its pressure and temperature. The gas leaves the compressor as a hot, high-pressure gas.

The compressor thereafter pushes the gas to the coils of a condenser which has fins. The condenser is present outside the house and there is a fan blowing atop the unit. The job of this fan is to blow cool outside air over the coil and through the fins. This process extractsheat from the hot refrigerant and throws it out in the environment. This heat in the refrigerant is also partly due to absorption of heat that was present in your house. The hot gas now changes into a warm liquid. The high pressure liquid reaches the expansion valve. At this juncture, it is turned into a cool, low-pressure liquid. The next station of the refrigerant from the expansion valve is the finned evaporator coil. This is in the indoor unit in case of a HVAC. For a window it is on the room side of the air conditioner unit.

At the evaporator, the pressure is much lower. The room air that is sucked in through ducts and passed through a filter is sent here. The hot room air passes over the evaporator coils. The cool refrigerant liquid present in the evaporator coil absorbs the heat and makes the air cool. The cool air is circulated again through ducts to rooms to make them cool. With the absorption, the refrigerant again changes into a cool, low-pressure gas. This is again drawn back into the compressor to continue the cycle.
